original

1. Not only new but the very first or one of a kind. Original implies 'genuine' but (unlike 'new') not necessarily 'unused,' and (unlike 'novel') not necessarily 'imaginative.'

2. Signed (executed) and, usually, stamped official document which may be reproduced as facsimiles. An original document can exist as two or more 'copies,' each one of them marked 'original' and having equal legal force.
